摘要：This paper provides a comprehensive analysis of the achievable point positioning accuracy for airborne LiDAR systems considering all the major potential error sources. Using the law of error propagation, rigorous analytical derivation of error formulas was performed to obtain a reliable assessment of the achievable point positioning accuracy. For practical use, based on the derived analytical formulas, accuracy figures and tables have been developed. In this paper select example figures illustrate the achievable point positioning accuracies of state-of-the-art LiDAR systems for various accuracies of the parameters that influence the LiDAR point positioning accuracy. The analytical derivation-based accuracy plots can also be used as a tool for choosing the right system or system configuration for a desired mapping accuracy, and to help the flight planning, i.e. selecting optimal flight parameters for a given system to achieve the desired point positioning accuracy. In addition, the developed error formulas can also facilitate the analysis of the effects of individual error sources on point positioning accuracy, although due to the size limitations of the paper this analysis is not included in this paper
